Maintenance Nursing the unconscious patient. Figure 28.3 Common causes of unconsciousness. In the absence of any facial, orbital or skull fractures, pressure is applied with the flat of the nurse’s thumb over the cranial nerve underlying the supraorbital ridge under the eyebrow (Figure 28.7a). However, the patient is able to control vertical eye movements and blinking and may be able to use these movements to develop a simple communication system. Coma may be defined as no eye opening on stimulation, Congenital deficits of the eye or previous enucleation (see Ch. Deep coma, the opposite of consciousness, is diagnosed when the patient is unrousable and unresponsive to external stimuli; there are varied states of altered consciousness in between the two extremes (Box 28.1). The feet should be kept at right ankles to the legs with a Figure 28.1 Mid-sagittal section of the brain, showing the reticular activating system and related structures. Hickey (2003) defines consciousness simply as ‘a state of general awareness of oneself and the environment’ and includes the ability to orientate towards new stimuli. how personal assumptions which we may not be aware of can lead to erroneous clinical decisions. The importance of maintaining such an equilibrium is beyond dispute, but die difficulty of understanding what unconsciousness is becomes a contributory factor towards inhibiting the nurse from extending the same totality of care she would offer the conscious patient, to one who is unconscious. The response usually includes spastic hand and wrist movements, with an inward rotation of the shoulders and forearms. Inability to open the eyes due to bilateral orbital oedema, tarsorrhaphy (where upper and lower eyelids are sutured together), or ptosis (palsy of cranial nerve III) should be recorded as ‘C’ (closed) on the chart. D. Abnormal flexion. Nurses are advocates of a patient. This is very different from spontaneous eye opening and should be recorded as ‘none’. Irrigate the eye with sterile prescribed solution to remove Patients with normal pressure hydrocephalus may be helped by insertion of a ventricular shunt (Wilson & Islam 2004, Vegetative state (VS) is a term used to describe a condition that may occur following a severe brain injury, where there is extensive damage to the cerebral cortex. Deterioration or improvement will depend on a number of factors such as the mechanism, extent and site of injury, age, previous medical history and length of coma. Monitor Intake and output chart accurately and record. Obtain a complete patient history including the … Involving the family in self care needs. The nurse needs to be aware if the patient has any hearing deficits because if their eyes are closed, this will affect the initial response. What is visual communication and why it matters; Nov. 20, 2020. 7 or less generally indicates coma Deep coma, the opposite of consciousness, is diagnosed when the patient is unrousable and unresponsive to external stimuli; there are varied states of altered consciousness in between the two extremes (, Anatomical and physiological basis for consciousness. Clean the ear with swab and dry carefully especially behind Orientated = scores 5. What is head trauma? Unconsciousness is a condition in which there is depression of cerebral function ranging from stupor to coma. 1999 Jul;92(7):353-5. Such localised defects are not generally regarded as a true altered state of consciousness, but this example highlights the difficulties in defining true conscious behaviour. Even during normal sleep, an individual can be roused by external stimuli, in comparison to the person in a coma. It provides a standardised approach to observing and recording adverse changes in the patient’s level of consciousness, so that appropriate action can be taken (, National Institute for Health and Clinical Excellence [NICE] 2003, Head injury: triage, assessment, investigation and early management of head injury in infants, children and adults, CT scanning based on presenting signs and symptoms, frequent and consistent neurological assessment to identify early signs of neurological deterioration, prompt referral and transfer to a specialist tertiary neurosurgical centre, early identification and clearance of cervical spine fractures, identification of non-accidental injuries. Neurological examination of the unconscious patient. Opening of the eyes implies arousal, but it must be remembered that this does not necessarily mean that the patient is aware of their surroundings. Neurological assessment in nursing is a critical skill for a neuro ICU nurse. An adequate airway must be maintained at all times. the RAS may first stimulate the cerebral cortex, and the cortical areas responding to reason and emotion may ‘modify’ the RAS, either positively or negatively, according to the ‘decision’ of the cerebral cortex. scale. The reticular formation (RF) and the reticular activating system (RAS) (Figure 28.1) are responsible for collating and transmitting motor and sensory activities and controlling sleep/waking cycles and consciousness. This is called the ‘arousal reaction’ and is the mechanism by which sensory stimuli wake us from deep sleep (Guyton & Hall 2000). LISTEN and FEEL for … Coma is an impaired state where the patient is totally unaware of themselves and their environment. Patient obtunded, assisting respirations. poor concentration or short-term memory problems, may only become apparent when a patient returns home. Impaired, reduced or absent consciousness implies the presence of brain dysfunction and demands urgent medical attention. The unconscious patient is completely dependent on the nurse to manage all their activities of daily living and to monitor their vital functions. In cycle B, impulses are sent down the spinal cord to activate skeletal muscles. Therefore, Lesions in this area can cause excessive sleepiness or even coma (, The cerebrum regulates incoming information by a positive feedback mechanism (Guyton & Hall 2000). Providing the patient has not sustained a cervical fracture, the ‘trapezius pinch’ (Figure 28.7b) is a useful alternative; the trapezius muscle (the large triangular muscle of the neck and thorax) is squeezed between the nurse’s fingers and thumb. Stimulation produces a diffuse flow of nerve impulses which pass upwards through the thalamus and hypothalamus, radiating out across the cerebral cortex to provoke a general increase in cerebral activity and wakefulness (see Figure 28.1). Common causes of altered level of consciousness are illustrated in Figure 28.3 (see, Cognitive disabilities, e.g. the specialised auditory and visual tracts (see Ch. E. Extending to pain. The National Institute for Health and Clinical Excellence (NICE) developed clinical guidelines for ‘Head injury: triage, assessment, investigation and early management of head injury in infants, children and adults’ (2003), revised 2005. Figure 28.5 Applying a peripheral painful stimulus: fingertip stimulation. This article aims to assist nurses … How to care for a patient's eyes in critical care settings Nurs Stand. Some neuro-rehabilitation units use a structured technique for assessing various sensory aspects of communication, movement awareness and wakefulness, known as SMART (sensory modality assessment and rehabilitation technique – www.smart-therapy.org.uk/), to enable clinicians to make a more accurate diagnosis of patients they suspect may be in PVS. Hearing can often be the last sense to be lost and the first one to come back before they are able to respond. Flexion to pain. Management of-unconscious-patient 1. Rationale: meets nutritional requirements of coma clients. Filed under Emergency … In response to a painful stimulus, the patient bends their elbow with adduction of the upper arms and abnormal posturing of the wrist and fingers, otherwise known as decorticate posturing. The verbal response may also be compromised by the presence of an endotracheal or tracheostomy tube. Injury to, or disease of, the cerebral hemispheres may cause diffuse damage that can inhibit or block the signals from the RAS, depressing the level of consciousness. It necessary insert oral airway for easy breathing. Both require a thorough assessment to determine the level of nursing care that they will need. A. Obeys commands (‘lift up your arms’). 2. It is the field that maintains quality of life in a community. The RAS is a physiological component of the RF and the neurones which radiate via the thalamus and hypothalamus to the cerebral cortex and ocular motor nuclei. 5. In cycle B, impulses are sent down the spinal cord to activate skeletal muscles. However, it is important to consider each of the three responses (eye opening, verbal response and motor response) separately, taking into consideration any communication difficulties (e.g. In the unconscious patient, airway obstruction may be caused by the soft palate or epiglottis (not by the tongue) when normal muscle tone is reduced (Resuscitation Council UK, 2011). The patient’s nursing care plan will also need to be re-evaluated and new goals for care set. Abnormal flexion. Signs and symptoms may include: Reduction in awareness reflects generalised brain dysfunction, as seen in systemic and metabolic disorders (see Figure 28.3). D. Abnormal flexion. For further information about PVS and locked-in syndrome, see Randall (1997), The need to assess conscious level may arise at any time, in any ward, in any hospital. of personal hygiene and care of pressure areas including prevention of foot The clinical condition of unconsciousness is one of complex physiology. In 1974, Teasdale and Jennett developed the Glasgow Coma Scale (GCS), a process used throughout the UK and worldwide as part of the neurological assessment and ongoing observation of the patient (see Figure 28.4). During the first few hours of coma, neurologic assessment is to be done as often as every 15 minutes. Confused = scores 4. It is this nucleus that sends inhibiting messages back to the thalamic nuclei using the neurotransmitter γ-aminobutyric acid (GABA). For further information about the use of the neurological observation chart and GCS in practice, see Woodward (1997a-, Nursing patients with musculoskeletal disorders, Nursing patients with disorders of the breast and reproductive systems, Nursing patients with respiratory disorders, Nursing patients who need palliative care, Alexanders Nursing Practice Hospital and Home. Early diagnosis and treatment with medication, and environmental changes such as reducing noise or sensory input may help to alleviate some of the symptoms. Gratitude in the workplace: How gratitude can improve your well-being and relationships This can be misleading and be a source of false optimism for relatives. Loosen the garments to allow free movements of the chest and suctioning, nasogastric tube or urinary catheter. The nurse observes and describes three aspects of the patient’s behaviour: Each of these is independently assessed and recorded on a chart (Figure 28.4). There is no international definition of levels of consciousness but, for assessment purposes, differing states of consciousness can be considered on a continuum between full consciousness and deep coma (Hickey 2003) (see, Impaired states of consciousness can be categorised as acute or chronic. However, almost any type of sensory signal can immediately activate the RAS and waken the individual, for example when daylight is detected by the retina of the eye, impulses are sent to the suprachiasmatic nucleus of the hypothalamus, activating sympathetic nerve fibres that will inhibit the secretion of melatonin in the pineal gland. Initiate appropriate initial management. Follow these steps for your next neuro assessment. Motor responses. This is termed a ‘positive feedback response’. Frequent suction is required to prevent the pooling of Figure 28.2 illustrates a number of activating pathways passing from the mesencephalon upwards. The need to assess conscious level may arise at any time, in any ward, in any hospital. In order to appreciate the importance of altered states of consciousness, a basic understanding of the physiology of consciousness is required. It may vary in degree but in its worse stage, no reaction of any kind is obtainable from the patient. The nurse should speak to the patient by calling their name and asking them to open their eyes. This indicates more severe dysfunction of the brain and is a poor prognostic sign. The patient opens their eyes when first approached, which implies that the arousal response is active.
